In conventional coal and gas fired fossil plants, boilers are the most likely source of a forced outage due to the wide array of damage mechanisms affecting tubes, headers and piping. Because of this, we have well-defined techniques to optimize reliability through condition assessment and lifecycle management of various boiler components.Get Price

period. In case of boilers with continuous blowdown, the heat loss due to blowdown should be calculated and added to the heat in steam. 1.6.3 Boiler Efficiency by Direct Method: Calculation and Example Test Data and Calculation Water consumption and coal consumption were measured in a coal-fired boiler at hourly inter-vals.Get Price
Generally water tube boilers are used for electric power stations. Fire Tube Boiler • The boiler is named so because the products of combustion pass through the tubes which are surrounded by water. • Depending on whether the tube is vertical or horizontal the fire tube boiler is divided into two types 1. Vertical tube boiler 2.Get Price

Working Principle. Both gas and oil fired boilers use controlled combustion of the fuel to heat water. The key boiler components involved in this process are the burner, combustion chamber, heat exchanger, and controls. The burner mixes the fuel and oxygen together and, with the assistance of an ignition device, provides a platform for combustion.Get Price

boilers will have equipment identical to this, but it is fairly typical of most systems apart from minor differences. To keep things simple we have chosen to describe a gas fired boiler. Pilot gas is supplied to the pilot burner through a pressure control valve and solenoid valve. Gas for the main burner is suppliedGet Price
The high-pressure steam from the boiler is expanded in nozzles to create a high-velocity jet of steam. The nozzle acts to convert heat energy in the steam into kinetic energy. This jet is directed into blades mounted on the periphery of a wheel or disc (Figure above).Get Price
